The system enables interoperability between the two carriers' eSIM systems, which adopt different vendors' subscription management platforms. Previously, for different carriers to reprogram the same eSIM, they had to adopt an eSIM system of one vendor. The new multi-vendor eSIM system announced today incorporates subscription management platforms of two different vendors - one by G+D Mobile Security that DOCOMO has adopted and the other by GEMALTO, which China Mobile has adopted.

China Mobile and DOCOMO have been jointly developing IoT technologies and related business based on the Strategic Cooperation Framework Agreement (SCFA). The new multi-vendor eSIM system is one of the results of this agreement.

Going forward, China Mobile and DOCOMO will continue developing services to enable corporate customers' products exported from Japan to China, such as automobiles, industrial equipment and agricultural machines, to smoothly switch from a Japanese carrier to Chinese carrier without replacing their SIMs.
